Apple CEO Tim Cook has said that the company won't be launching a bigger iPhone until building one doesn't require any 'trade-offs' in order to accommodate a larger display.

Speaking at Apple's quarterly earnings call on Tuesday, Cook said: "My view continues to be that the iPhone 5 has the absolute best display in the industry. We always strive to create the very best display for our customers."

Earlier this year, Barclay's Capital analyst Ben Reitzes said that Apple should launch a bigger iPhone, which he dubs 'iPhablet', because he expects the larger phone market to dominate smartphone shipment growth into 2015.

Apple's iPhone 5 has 4in screen, which is already bigger than the 3.5in display found in previous models, but many competing smartphones are launching with even bigger screens.
